Software, Everywhere

From wrist watches to the Space Shuttle,software is everywhere

Every day, millions of lines of code are writtenby thousands of software developers around the world

Our society becomes more dependent on softwareevery passing day

Increasing Software Complexity

70's 90's 2010

Cell Phone - 100.000 10.000.000

High-End Car 100.000 1.000.000 100.000.000(GM/IBM Estimates)

Word Processor - 78.000(Word 4.0 DOS)

50.000.000+(Windows Vista)

Evolution in lines of code on typical systems

Every system, every application, in every version,in any domain, gets more complex at each iteraction


5/86

Increasing Software Demand

Demand for software is skyrocketing

More and more traditional tasks are being

assisted or replaced by software

Today, most consumer devices have some sort

of software running inside. A growing trend.

Disposable computing is not far away...


6/86

Increasing Challenges

- Compliance regulations (HL7, Sarbanes-Oxley, HIPPA)

- Multi-core & Multi-threading

- Development paradigms (SOA, Web 2.0, SaaS, cloud computing)

Software makers need to address the evolution in:

And at the same time face:

- Decreasing time-to-market

- Decreasing budgets

Software development

is anever-growingchallenge...

Whathave we done

so farto address this?

Problem : Slow tool evolution

In the seventies,people developed software line-by-line, file-by-file

Four decades later,most people still develop software line-by-line, file-by-file

While there has been some evolution in development methodsand tools, most are essentially based on flat source files.

Problem : Feature Traceability

The traceability problem occurs when the solution features that implement a problem

feature cannot be easily identified.

This makes it hard to identify all of the things that need to change in theimplementation, and to ensure that all of the changes are made consistently, whenthe requirements change.

Failing to trace all elementsthat belong to a given featureleads to bugs, inconsistencies,and excess time.

It's a (too) common scenario.

Which?

13/86

In the recent past, several promises have emerged,claiming to be the silver bullet to the software crisis.

But many have failed, or simply did not deliver.

Let us have a look into the most important ones:(Quoting the opinion of others)

Failed Promises


14/86

#1 : UML Unified Modeling Language

UML has become complex and clumsy. For 80% of all software only 20% of UMLis needed. However, it is not easy to find the subset of UML which we would callthe Essential UML.

Ivar Jacobson, Co-Inventor of UML, June 2009

UML is applying an abstraction at the wrong end of the problem. It isprimarily used to sketch object models for inferior languages. As such,it tends to explode into incomprehensible patterns of accidentalcomplexity in order to accommodate the various design patternsthat are used work around the lack of essential language features.

Because the UML models cannot be compiled, executed, or

interpreted, they are reduced to the level of mere documentation. Assuch, it is generally not even worth keeping in sync the manualround trip from the code to the model and back is just too expensivefor something that adds no more value to a project than an elaboratecode comment.From lispy.wordpress.com


15/86

#2 : MDA Model-Driven Architecture

At its most basic, MDA involves transforming one UML model into another UML model, possiblyseveral times and possibly automatically [...]. The MDA approach leads to the same results aswizards: lots of code (and models) that you didnt write yourself but that you are expected tomaintain. The MDA idea gets even worse when you consider round-trippingwould you like to

update the manually made changes to the code and lower level models back to all the higher-levelmodels?

MDA is limited to the effectiveness of the UML as a language for model driven development,a task it was not designed to support.

Jack Greenfield - Microsoft

Unfortunately, early enthusiasm for Model Driven Architecture (MDA) has dissipated to thepoint that many people are openly skeptical of the value of any model-driven approach.

From MDA Redux, by Alan Brown, published by IEEE Computer Society

#3 : DSLs - Domain-Specific Languages

[...] the Tower Of Babel* effect that results from having so many languages that a person needs tobe familiar with (if not master) in order to get common jobs done.

... nothing is better than having your own Little Language to do a specific job. It allows for conciseexpression of solutions to specific problems. But a problem arises when The Next Guy comes alongand has to learn the concepts behind the language, the motivations for particular elements of it,

the syntax, etc.

Writing a decent DSL is hard. Very limited, very simple DSL's can be adequately produced by acompetent programmer with expertise in the problem domain - DSL's that can be described on apage or two, and are tailored to a specific application/environment. These language are seldomusable outside the very limited context.

But writing a good DSL that is robust and reusable beyond a limited context, is a lot of work. Itrequires persons with both domain expertise and language design expertise (not necessarily thesame person) to pull off. A truly reusable DSL will require reasonable documentation, otherwise itwon't survive the departure of its designers. And, it will eventually require a good set of tools -debugging environments and the like - for it to become worthwhile.

Forrester expects model-driven development (MDD) to play a key role in the future of softwaredevelopment; it is a promising technique for helping application development managers address

growing business complexity and demand.

Gaining Momentum : MDSD and DSM

Diego Lo Giudice Forrester Research

Unlike MDA, MDSD (Model-Driven Software Development) and

DSM (Domain-Specific Modeling) follow a more pragmatic, lessformal approach to software modeling. That makes theseapproaches more accessible to the mere developer.

Domain-Specific Modeling raises the level of abstractionbeyond programming by specifying the solution directly using

domain concepts. The final products are generatedfrom these high-level specifications, because both the modeland generators fit the requirements of only one company anddomain. Your experts define them, your developers use them.

ABSE - Overview

HowcanABSEaddresstoday'ssoftwaredevelopmentproblems


19/86

Quick Facts

- Stands for Atom-Based Software Engineering

- Is a generative approach (generates code from models) to

MDSD (Model-Driven Software Development) and DSM (Domain-Specific Modeling)

- Relies on tree-based models

- Is a cross-platform Integrated Development Environment (IDE)

- Implements and extends ABSE

ABSE

AtomWeaver


20/86

A software engineering project is made up of Atoms, organizedas a tree. That tree is the Project Model.

The ABSE Tree

< A partial view of AtomWeaver's ABSE model

A tree conveys association, mimicking

the associative human brain, thereforebeing able to represent and decomposeany problem or data structure.

The tree is ABSE's supporting paradigm,allowing the model to think like us.

22/86

Atom Types

There are only three types of Atoms:

Atom Organizer Organizes library contents into meaningful structures

Atom Template The metamodels (building blocks) of any ABSE model

Atom Instance The actual models that make up a project model


23/86

Atom Libraries

An Atom Library contains Atom Templates, possibly structured in ameaningful way through Atom Organizers.

Any ABSE model must be built fromone or more libraries as it canonly contain Atom Instances. Root Lib

Language Lib

Platform Lib

Domain Lib

DomainComponents

Libraries can use or extendother libraries.

ProblemDomain

SolutionDomain

We can raise the abstractionlevel everytime we extenda library.


24/86

The Atom Libraries are the driving force behind ABSE.

A good library can help you save many development hours,and even more test hours.

Atom Libraries

The vision behind Software Product Lines (SPL) is that once the

company's domain is converted into models, they can bereused and combined to create similar, but different, systems.

ABSE and its libraries help SPL's become a reality.

Libraries can be exchanged between systems throughALX (AtomWeaver Library Exchange) files.


25/86

ABSE is Universal

It can support and combine all forms of software engineering,including:

Traditional file-oriented methods Literate Programming

Aspect-Oriented Programming

Component-Based Development

26/86

ABSE is Universal

This is possible because ABSE...

is not targeted to a specific language, architecture, or platform

allows generation of any kind of text or data

has a very flexible meta-metamodel

uses association as its paradigm, the basis of human thinking


27/86

ABSE is Domain-Agnostic

Enterprise Defense Systems AutomotiveAerospace

ABSE can be applied to virtually any domain.

Horizontal (solution domain) libraries can beextended with vertical (problem domain)libraries to achieve reductions in time-to-market and savings on development andtesting efforts.

Atoms can represent and generate code forspecific aspects of the target domain.

Entertainment Engineering

Embedded Devices

ABSE is Language-Independent

FortranHaskellEiffelC#PhytonSQLJavaABAPErlangScalaSmalltalkVHDLPrologC++

AdaPascalPHPLispRubyJavaScriptDelphiSASCOBOLCamlTclDVisualBasicCGroovyML

Being largely based on text generation,ABSE can generate all kinds of textualoutput, from plain text files to completesoftware systems.

A single ABSE project can target multiplelanguages and file types.


29/86

ABSE is Refactorable

ABSE metamodels can evolve with your skill.

You can start doing just some texttransformation, grow up by refactoring

Metamodels into common patterns.

You can continue right up to fullDomain-Specific Modeling andSoftware Product Lines.

Each time you derive an Atom Template intoanother Template, you increase theabstraction level.

30/86

ABSE is Easy

You don't need to be a rocket scientistto apply in an effective way.ABSE is accessible to the "mere developer mortal".

An ABSE project is like a large mechanismthat can built from smaller, pre-built orcustom parts.

The ABSE approach is more pragmatic and simpler than otherDSL/model-driven tools or technologies like oAW, OMG'sMDA/MOF/XMI, Eclipse EMF/GMF, Microsoft OSLO/M, Xtext.


31/86

ABSE is Complete

ABSE meta-metamodeldesigned to support 100%code generation from themodel.

No round-trip necessary.

The mix of custom andgenerated code is directlysupported by the meta-metamodel.

No worries aboutoverwritten custom code,no management issues.

ABSE is Manageable

An ABSE model can grow togenerate multi-million lineapplications, and still be easyto manage.

That's because ABSE is based ona tree and not on a graph:

Tree branches easily encapsulateother branches.

A complex application using a graph


33/86

ABSE is Comprehensive

The complete ALM (Application Lifecycle Management)

cycle can be supported.

An ABSE tree is not exclusive to software implementation:it can also represent processes, documentation, SCM, etc.

34/86

ABSE is Collaborative

Due to its granular nature,an ABSE model can beconcurrently manipulated.Two or more developers canwork on the same ABSE model.

And through a supporting tool(like AtomWeaver), workflowscan be applied. Individual atomsor tree branches can bechecked-in or out, versioned andconditionally enabled/disabled.

ABSE in the Enterprise

HowcanABSEimprovesoftwareengineering


36/86

ABSE Can Bridge All Stakeholders

By making available the appropriate Templates to each stakeholder,domain experts, designers, developers and testers can worktogether on the same ABSE model.

Domain experts can specify Designers can design & re-arrange Developers can build Testers can debug & test


37/86

ABSE Captures & Shares Knowledge

The company's domain knowledge and the team's developmentknowledge can be captured into ABSE metamodels.

Benefits:

- Individual expertise can be shared with the whole team

- Less skilled developers can work like the experts

- Architectural uniformity can be achieved

- Best practices are easily disseminated and enforced


38/86

ABSE Increases Productivity

- Repetitive patterns- Repetitive coding- Repetitive changes- Interfacing code/specification- Unit test preparation- Debug/log/trace code

These and many other boring and error-prone tasks canbe reduced or even completely eliminated by using amodel-driven approach like ABSE.

Some tasks under manual coding simply cannot scale:


39/86

ABSE Increases Productivity

Each time an ABSE metamodel is instantiated, time is saved.

Each time an ABSE metamodel is extended, more time is saved.

The team's productivity potential increases whenever it addsanother metamodel (Atom Template) to the ABSE library.Working on a higher abstraction level boosts your productivity.


40/86

ABSE Increases Quality of Code

The code produced by the ABSE metamodelscan (and should) be tried and tested code.

By reducing the amount of custom code usedin the model, overall code quality increases.

It is known that more time is spent debuggingcode than actually writing it.


41/86

Critical Innovation : Software Reuse

To realize a return on the investments we make in developing the solutions, we must reuse themenough to more than recover the cost of their development, either directly through cost reductions,or indirectly, through time to market reductions and quality improvements.

Jack Greenfield et al - Software Factories

Systematic software reuse is a promising means to reducedevelopment cycle time and cost, improve software quality, andleverage existing effort by constructing and applying multi-useassets like architectures, patterns, components, andframeworks.


42/86

ABSE Promotes Reuse

ABSE's meta-metamodel allows Atom Templates to be aggregators,so you can turn any part of your project into a new template forfuture reuse.

Project A

Instance A

Instance B

Instance C

Library A

Instance A

Instance B

Instance C

Template 1

Project B

Instance D

Instance 1

Instance E

Instance F

The most common type of reuse is the reuse of software components, but

other artifacts produced during the software development process can alsobe reused: system architectures, analysis models, design models, designpatterns, database schemas, web services, etc.

ReuseTemplatization

In the same way, ABSE lets you turn recurring patterns intotemplates, reducing project complexity and maintenance costs.

That's because youonly have to maintainone instance of yourcode. All otherinstances of that code

are automaticallyupdated.

And since manual codeis natively supported,there's no need to

waste time maintainingprotected regions,code guards and othertrickery, just tomaintain the integritybetween manual andgenerated code.

The Instance's Creation Condition

The inclusion of each Atom Instanceon the project can be subject to anexpression that dictates whether thatAtom is executed or not.

If the evaluated condition is false, the

Atom becomes invisible to the project.

This brings more flexibility to thegeneration process and allows templatesto include/exclude some of their auto-generated atoms based on user-suppliedvalues.

Instance Relocation

Atom Instances that are auto-generated by

an Atom Template can then be relocated toanother position on the model tree.

The relocated atom may be again movedby the user, if it is not blocked.

For instance, user interface programmers may create atoms thatwill automatically create the interface visual elements's atoms.

Designers can then manipulate and edit those atoms to achievethe desired application visuals.

ABSE Strength #1 : Inheritance


53/86

ABSE Strength #1 : Inheritance

Like classes in several programming

languages, Atom Templates can bederived into more complex andspecialized Templates.

This allows you tobuild metamodelsthat share commonconcepts.

cpp_class

gui_dialog ext_data_object

db_persistent_object

root_default

The derived template will inherit allproperties and code from its base template.

ABSE Strength #2 : Composition


54/86

ABSE Strength #2 : Composition

Atoms can be combined to build larger structures.

Atom Instances are combined to build the Project Model.

Atom Templates can be composed of several other Templates which,on their turn, can also be composed of other Templates.

From Wikipedia:http://en.wikipedia.org/wiki/Object_composition

Composited (composed) objects areoften referred to as having a "has a"relationship. A real-world example ofcomposition may be seen in anautomobile: the objects wheel,steering wheel, seat, gearbox and

engine may have no functionality bythemselves, but an object calledautomobile containing all of thoseobjects would serve a higherfunction, greater than the sum of itsparts.

Actual metamodels from AtomWeaver project


You can see here how a metamodel of

a C++ class, composed of two AtomInstances, is derived into anextended class with addedfeatures. Then a C++ Componentmetamodel is defined byinheriting Extended Classand adding data andconfigurationfeatures...



56/86


Then a Persistent

Componentmetamodel wascreated by inheritinga C++ Componentmodel and addingspecific DB features.

The same was doneto create a DatabaseDocumentmetamodel.



57/86

You can implicitly generate dozensor even hundreds of atoms just byadding a single atom instance to

the project.

If each of those atoms generatesjust a few lines of code...

Imagine how much code that canbe generated at once!

Now imagine that the generatedcode is mature, tested, quality

code...

ABSE is an Executable Model


59/86

ABSE is an Executable Model

Every Atom on the ABSE Tree has its own transformation code(acquired from its template).

To generate code, the Model Treerecursively executes its atoms,

which is equivalent to say that all

atoms are executed from top tobottom.

The tree is executed four times,and on each iteraction one of thefollowing Atom Template sectionsis executed:

AtomWeaver is an ABSE Model


62/86

AtomWeaver is being developed through an ABSE Model.

AtomWeaver is ABSE's proof-of-concept, showing that afairly sophisticated application can be easily built using amodel-driven approach like ABSE.

Some statistics:

(Current version of AtomWeaver Prototype)

- 38000 Total Atoms- 7800 User-Created Atoms- 30200 Auto-Generated Atoms

- 334 Atom Templates in Library- 2456 Atom Instances in Model

- 174756 Lines of Generated (+ Manual) Code- 701 Generated Files

AtomWeaver is presently the market's only plug-and-play MDSD system

No other present system lets you start creating models in a few minutes

AtomWeaver : The Universal Generator


65/86

Besides pure programming,

the modern software vendorfaces a long list of otherperipheral, but equallyimportant activities:

- Requirement management- Research

- Change management- Building- Testing- Version control- Issue management- Internal/customer reporting- End-user documentation- Code revisions

- Installer packaging- Application resources- Databases- ...

Why use separate tools?

AtomWeaver can be the centralpoint of all development activities.

Using AtomWeaver's modeling andgeneration capabilities, it'ssurprisingly easy to:

- Build your own bug tracker- Implement code coverage- Automate documentation- Build synch'ed intranets/websites- Create configurations/build files

- Package resources- Automatically build tests- Embed debug/trace code- Refactor features/architecture

AtomWeaver Modules


66/86

AtomWeaver is composed of several mandatory and optionalmodules. Each module contains a different aspect of the project.

Future AtomWeaver versions will allow the creation of other,

custom-defined modules through its API.

Library, Model, Files and Log are the mandatory modules. Allothers are optional.

AtomWeaver Modules


67/86

Documentation For development support documentation, drafts, etc.

Library Contains all libraries loaded into the project

Model Holds the project's main model

Files Lists and manages all generated artifacts

Issues Manages SCM operations (bug tracking as the most common)

Help Builds and concentrates all end-user documentation

Log Registers all that is happening in AtomWeaver

AtomWeaver's Model Transformation DSL: Lua


68/86

Instead of using an exotic, custom DSL, AtomWeaver uses Lua to

transform ABSE models into final source code.

Lua is a lightweight, reflective, imperative and functionalprogramming language, designed to be a scripting language.

Several benchmarks show Lua as the fastest interpreted scriptinglanguage available.

This is specially important to code generation where millions oflines of transformation code are typically needed on a large project.

AtomWeaver Extends ABSE


69/86

AtomWeaver adds tools and commands to ABSE's basic featuresetto improve the developer's experience and productivity, including :

Atom Dictionary: Lets you reference any project Atom byits associated name.

Atom Lists : Lets you categorize atoms and build lists accordingto your pre-defined criteria.

Counters : Lets you use unique values project-wide.

AtomWeaver editions

These libraries can be supplied by:

- Individual users- Commercial vendors- Isomeris

By using ready-made libraries, you save time and get qualitycode and models from the domain experts.

Team Edition Feature:Concurrent Model Edition


75/86

Concurrent Model Edition

The project is stored on a central database

Developers can load a copy of the project into their workstations

An Atom or a branch can be checked-out for edition. Other users

are denied write access to that atom or branch

After check-in, changes are incorporated into the central database

AtomWeaver regularly checks for new updates and automaticallyloads them to the local copy of the project

Team Edition Feature:Developer Role Management


76/86

Developer Role Management

The structure of a development team is mimicked in theAtomWeaver environment

Each user must log in to work on a project

The two main roles are Architects and Developers. Other rolescan be created

Each role can have different privileges regarding code accessor changes

Developer roles are also useful for workflows

Team Edition Feature:Model Versioning


77/86

Model Versioning

Like in a source control system, atoms can be versioned

Branches/forks can be made

Past project snapshots can be obtained

Atoms can be reverted to a previous version

Summary

SummingupABSE&AtomWeaver

ABSE aims to lead the MDSD movement


82/86

MDSD is recognized as the next revolution in the Software

Engineering industry, and is gaining momentum among largerorganizations.

However, complexity in its various implementations prevents itfrom gaining mainstream adoption.

ABSE aims to lead MDSD adoption by:

- Defining a very light meta-metamodel- Having a small set of rules- Being flexible (can mix custom and generated code)

- Having a reference implementation (AtomWeaver)

AtomWeaver aims to compete with otherhigh-end IDE's


83/86

high end IDEs

MS Visual Studio and Eclipse are the major players in thegeneral-purpose software IDE segment

AtomWeaver can differentiate itself by:

- Its unique development approach (ABSE)- A high adaptability to very specific industries and domains- Having lower licensing costs

Reality Check !


84/86

ABSE still in its infancy

AtomWeaver is still just a bare-bones IDE

Developer mindset inertia is a respectful opponent
